Current capacitive methods and structures for reducing noise on an integrated circuit (IC) are not always adequate. For example, previous implementations of capacitance would include a capacitor residing on the circuit board or package containing the device. Such capacitance is inherently inferior to a capacitance directly resident on the semiconductor device because it is isolated by the board and package inductance, thus severely reducing its effectiveness in providing noise immunity. Another prior art method is to include capacitors on an integrated circuit but place the capacitors far from the switching logic in which it is to reduce noise (usually capacitors are positioned at the periphery of an IC, and not in standard cell layout blocks). Again, other capacitances, line resistance, inductance, timing delays, and physical separation reduce the effectiveness of this technique. In other words, by not being located immediately adjacent to the standard cells, a significant amount of resistance (etc.) exists between the capacitor cells and the actual switching logic. This reduces the amount of transient current the capacitor can provide, which limits its noise suppression capability and will slow down the speed of the switching circuits. Widening the metal conductors connecting the switching logic to the capacitor cells would overcome this, but at the expense of device area consumed by the widened power and ground buses. Another prior art method is to use the inherent capacitance in the well and substrate normally present in the spacer cells of a standard cell block as the capacitor cell. The severe drawback to this is the total amount of capacitance provided is not nearly enough to suppress any noise appearing on the power and/or ground conductors. At least two orders of magnitude greater capacitance must be provided to accomplish a reduction in power and ground noise.
